Influence of Inorganic Phosphorus Forms on Calcareous Soil under Different Fertilization Systems in Northern China
Effect of the inorganic phosphorus forms by different fertilization system were studied in this experiment.The result showed that the content of Ca2-P,Ca8-P,Al-P,Fe-P increased significantly,improved by 16.3％～23.2％,6.76％～10.03％,4.04％～6.45％,7.12％～11.42％ respectively compared to no fertilizer(CK),and Ca10-P,O-P changed not obviously.The content of Ca8-P,Al-P of Mineral fertilizer + fowl manure+phosphor bacterial fertilizer(NP+M+B) treatment improved obviously,and the dissolution of Ca10-P also promoted.The content of Ca2-P,Fe-P of Mineral fertilizer+fowl manure(NP+ M) accumulated effectively.Treatment of mineral fertilizer+fowl manure+phosphor bacterial fertilizer or mineral fertilizer+fowl manure inhibited the content of O-P better than the fowl manure(M) and mineral fertilizer(NP).Mineral fertilizer improved the content of Ca2-P,Ca8-P,the effect of manure treatment was lower.Maize yield of mineral fertilizer+fowl manure+phosphor bacterial was the highest,and was significant different with mineral+manure.The correlation of yield and the content of Ca8-P,Fe-P,and yield of manure treatment was the minimum.Above of all,phosphor bacterial fertilization had obvious effect on the Ca8-P,Al P,Ca10-P,O-P,the order of the effect of different treatments was that mineral+ manure+phosphor bacterial＞mineral+manure＞mineral＞manure＞no fertilizer.
